In this embodiment, the target video may be a video that the user needs to play, and the target video may be played through a video player or a browser. The target video is played in a double-speed playing mode, for example, the target video is played at an accelerated speed twice the original playing speed.

Optionally, a target request is sent to the server, where the target request is used to request to obtain a Uniform Resource Locator (URL) of the target video. After the URL of the target video is obtained, the target video is obtained according to the URL, for example, a video stream of the target video is obtained.

Optionally, the target video of this embodiment comprises media package data and audiovisual data. And analyzing the media packaging data and the audio and video data in the target video, and if the target video is played in a normal playing mode, playing the target video until the end.

Optionally, if the target video is played in a double-speed playing manner, the first video frame to be played in the target video may be acquired within a unit time, where the unit time may be 1 second, and the video frame in the target video is an image frame in the target video. In the case that the current playing speed of the target video does not satisfy the double speed requirement, the tag of the first video frame is obtained, for example, the target video is decoded, and the tag of the first video frame is obtained from the obtained decoded data, and the tag of the first video frame may be used to indicate the content type of the first video frame, for example, the content type is a person, a landscape, a gunfight, a martial arts, a love, a beauty, a man, and the like, without any limitation here.

And step S204, skipping the playing of the first video frame under the condition that the label of the first video frame is different from the preset target label.

In the technical solution provided in the above step S204, after the tag of the first video frame to be played in the target video is obtained, whether the tag of the first video frame is the same as the preset target tag is determined, and whether the tag of the first video frame is the same as the preset target tag may be determined in the scene matching module. And if the label of the first video frame is not the same as the preset target label, skipping the playing of the first video frame.

In this embodiment, the preset target tag may be an interest tag of the user, and is used for indicating the interest of the user. Optionally, the data indicating the viewing behavior of the user is counted by the backend server, and the interest of the user is calibrated to obtain a preset target tag, where the preset target tag may be used to indicate any one of people, scenery, gunfight, martial arts, love, beauty, and spirit, and is not limited herein.

After the label of the first video frame is judged to be different from the preset target label, if the label of the first video frame is different from the preset target label, it is indicated that the content type indicated by the label of the first video frame is not in accordance with the interest of the user, that is, the video content presented during playing of the first video frame is not the video content in which the user is interested, the playing of the first video frame is skipped, for example, the plot of the video in which the user is not interested is skipped at high speed, so that the observability of the target video is improved, and the efficiency of the target video during double-speed playing is improved.

And step S206, under the condition that the label of the first video frame is the same as the target label, playing the first video frame according to the target playing speed.

In the technical solution provided in the foregoing step S206 of the present application, after determining whether the tag of the first video frame is the same as the preset target tag, if the tag of the first video frame is the same as the target tag, the first video frame is played at the target play speed, where a difference between the target play speed and the original play speed of the first video frame is within a first target threshold.

In this embodiment, if the tag of the first video frame is the same as the target tag, it indicates that the content type indicated by the tag of the first video frame matches with the interest of the user, that is, the target tag matches with the tag of the first video frame, the video content presented during playing of the first video frame is the video content interested by the user, and the first video frame may be played at the target playing speed, that is, the video content of the first video frame interested by the user may be played at the target playing speed. Optionally, the first video frame is played at its original play speed or at a slightly faster speed.

Optionally, in a case that the target video already meets the current speed doubling requirement, the first video frame may be played at the original playing speed of the first video frame; under the condition that the target video frame does not meet the requirement of the current speed doubling, the number of video frames needing to be skipped to meet the set speed doubling value can be determined according to the set speed doubling value, the number of skipped video frames is obtained, the difference between the number of the video frames needing to be skipped and the number of the skipped video frames is determined as the number of the video frames needing to be skipped, the target playing speed for playing the first video frame is determined according to the number of the video frames needing to be skipped, the target playing speed is slightly higher than the original playing speed, but the target playing speed and the original playing speed are within a first target threshold value, so that the user cannot influence the user to watch the interested video content in the target video.

Optionally, in this embodiment, in a unit time, when the number of skipped video frames reaches the number of video frames that need to be skipped corresponding to the double speed value of the target video, the remaining unplayed video frames in the unit time may be played normally, and the remaining unplayed video frames may include video frames that are interesting to the user or may include video frames that are not interesting to the user; if the determined frame number of the skipped video frame does not reach the video frame number which needs to be skipped and corresponds to the double speed value of the target video in unit time, the motion compensation module can be further entered, the frame skipping is selected according to the similarity between the adjacent video frames, one video frame in the two adjacent video frames with high similarity is skipped, and the other video frame is played, so that the video frame which needs to be skipped and the video frame which needs to be played in unit time are determined, and the playing speed of the target video in the double speed playing is met.

And in the next unit time, the skipping or the playing of the video frame of the target video can be selected according to the method, so that the content which is interested by the user in the target video is displayed to the user to the maximum extent, and the efficiency of the video in double-speed playing is improved.

Through the steps S202 to S206, in the process of performing double-speed playing on the target video, a tag of a first video frame to be played in the target video is obtained, where the tag of the first video frame is used to indicate a content type of the first video frame; skipping the playing of the first video frame under the condition that the label of the first video frame is different from the preset target label; and under the condition that the label of the first video frame is the same as the target label, playing the first video frame according to the target playing speed, wherein the difference between the target playing speed and the original playing speed of the first video frame is within a first target threshold value. After the target video is played at the double speed, skipping the first video frame with the label different from the preset target label, and playing the first video frame with the label same as the preset target label at the target playing speed, that is, skipping the video frame which is not interested by the user, and playing the video frame which is interested by the user at the target playing speed, so as to avoid fixed skipping of a certain number of video frames, which causes the video frames which are interested by the user and not interested by the user to be skipped the same, and influence the efficiency of the video in the double speed playing, thereby realizing the technical effect of improving the efficiency of the video in the double speed playing, and further solving the technical problem of low efficiency of the related technology in the double speed playing of the video.

As an alternative implementation manner, after the playing the first video frame at the target playing speed in step S206, the method further includes: and skipping the playing of the second video frame when the similarity between the second video frame and the first video frame is larger than a second target threshold, wherein the second video frame is the next video frame of the first video frame in the target video.

In this embodiment, in a unit time, after the first video frame is played at the target playing speed, a next second video frame in the target video frame is acquired, that is, the second video frame and the first video frame are two consecutive video frames in the target video, and the similarity between the second video frame and the first video frame can be acquired. Optionally, the similarity between the second video frame and the first video frame is determined according to a correlation between the second video frame and the first video frame. After the similarity between the second video frame and the first video frame is obtained, it is determined whether the similarity between the second video frame and the first video frame is greater than a second target threshold, which may be determined according to a double speed value of the target video at the current playing time, for example, a frame skipping coefficient V0 is determined according to the double speed value, and a product between the frame skipping coefficient V0 and a target value T0 is determined as the second target threshold. After judging whether the similarity between the second video frame and the first video frame is greater than the second target threshold, if the similarity between the second video frame and the first video frame is greater than the second target threshold, the second video frame can be determined to be a redundant video frame of the first video frame, and the playing of the second video frame is skipped, so that the wonderful content in the target video is displayed to the user to the maximum extent, and the efficiency of the video in double-speed playing is improved.

Optionally, in the embodiment, the first video frame and the second video frame to be played in the target video may also be simultaneously acquired in the process of performing double-speed playing on the target video. Under the condition that the similarity between the first video frame and the second video frame is larger than the second target threshold, the similarity between the first video frame and the second video frame can be determined to be higher, one video frame with higher video quality is selected from the first video frame and the second video frame to be played, and the other video frame is skipped to be played, wherein the video quality can be the definition of the video frame during playing and the like, and other parameters which can be used for indicating the playing quality of the video frame and the like, so that the wonderful content in the target video is displayed to the user to the maximum extent, and the efficiency of the video during double-speed playing is improved.

Optionally, in the embodiment, in the process of performing double-speed playing on the target video, a plurality of video frames including the first video frame and the second video frame may be simultaneously acquired, and when the similarity between the plurality of video frames is greater than a second target threshold, it may be determined that the similarity of the plurality of video frames is high, and one video frame with the highest video quality is selected from the plurality of video frames to be played, and the playing of other video frames is skipped, so that the highlight content in the target video is maximally presented to the user, and the efficiency of the video in double-speed playing is improved.

As an optional implementation manner, before skipping the playing of the first video frame in step S204, or before playing the first video frame at the target playing speed in step S206, the method further includes: acquiring a tag set, wherein the tag set comprises a plurality of target tags, each target tag is used for indicating one viewing interest of a target object, and the target object is an object for viewing a target video; in the case that the tag of the first video frame and the target tag are not the same, skipping playback of the first video frame includes: skipping the playing of the first video frame under the condition that the label of the first video frame is different from the plurality of target labels in the label set; under the condition that the label of the first video frame is the same as the target label, playing the first video frame according to the target playing speed comprises the following steps: and under the condition that the label of the first video frame is the same as one target label in the label set, playing the first video frame according to the target playing speed.

In this embodiment, the tag set includes a plurality of target tags, each of which is used to indicate a viewing interest of the target object, for example, the viewing interest of the target object may be a person, a landscape, a gunfight, martial arts, love, beauty, a man, etc., without any limitation. The target tag set may be obtained by counting the viewing behavior of the target object, for example, counting the viewing behavior of the target object, and calibrating the viewing behavior of the target object, for example, calibrating the viewing behavior to be people, scenery, gunfight, martial arts, love, beauty, and the like, so as to obtain a plurality of target tags, and during the target video double-speed playing process, comparing the tags of the video frame with the plurality of target tags in the tag set.

In the process of target video double-speed playing, under the condition that the tag of the first video frame is different from a plurality of target tags in the tag set, that is, the tag of the first video frame does not accord with the interest of the target object counted at present, the first video frame may be a video frame which is not interested by the target object, and the playing of the first video frame is skipped at this time. Under the condition that the label of the first video frame is the same as one target label in the label set, the first video frame is consistent with one interest of a target object which is counted at present, the first video frame may be a video frame which is interesting to the target object, and the first video frame is played at a target playing speed, for example, the first video frame is played at an original playing speed or at a speed slightly higher than the original playing speed, so that a highlight segment in the target video is displayed to a user to the maximum extent, the efficiency of the video in double-speed playing is improved, and the experience of the user in watching the target video is further improved.

As an optional implementation, obtaining the tag set includes: the method comprises the steps of obtaining a tag set sent by a first server, wherein the tag set is generated by the first server according to historical viewing behaviors of a target object, and the historical viewing behaviors are associated with viewing interests of the target object.

In this embodiment, the target tag set may be obtained by a behavior statistics module, for example, by counting, by the first server, the viewing behavior of the target object, and the background server may collect a large amount of data indicating the viewing behavior of the target object, where the viewing behavior is associated with the viewing interest of the target object, for example, the viewing interest of the target object is landscape, the viewing behavior of the target object is video in a landscape class, or web pages in a landscape class, or the like, that is, the viewing interest of the target object corresponds to the viewing behavior of the target object. The embodiment may calibrate the viewing behavior of the target object by the first server, thereby obtaining a tag set comprising a plurality of target tags. The first server may be a background server.

As an alternative implementation, after skipping the playing of the first video frame in step S204, or after playing the first video frame at the target playing speed in step S206, the method further includes: responding to the target operation instruction, and playing the video in the target playing progress in the target video; and adding a label of the content type of the video indicating the target playing progress to the label set so as to update the label set.

In this embodiment, the tag set including the plurality of target tags may be updated after skipping playback of the first video frame or after playing the first video frame at the target playback speed. And acquiring a target operation instruction, where the target operation instruction may be an operation instruction generated when the target object readjusts the playing progress of the target video to the target playing progress after the target video is played at the double speed, for example, an operation instruction generated when a user drags to a relevant playing position of the target video again for watching is obtained. Responding to the target operation instruction, playing the video at the target playing progress in the target video, wherein the video at the target playing progress can be the video content interested by the target object, acquiring a label of the content type of the video for indicating the target playing progress, such as people, scenery, gunfight, martial arts, love, beauty, and the like, adding the label of the content type of the video for indicating the target playing progress to the label set to update the label set, so that whether the video frame is the video frame interested by the target object is judged by comparing with the label of the video frame in the process of target video double-speed playing, whether skipping is determined, thereby maximally satisfying the condition that the user watches the interested content when the video is played at double-speed, protecting the wonderness of the video content, and improving the watching performance of the video, the efficiency of the video in the double speed playing is improved.

As an optional implementation manner, the target playing progress is used to indicate a position of an unplayed video in the target video, or to indicate a position of a played video in the target video.

In this embodiment, the target playing progress may be used to indicate a position of an unplayed video in the target video, for example, a user knows that video content in a certain period of unplayed video in the target video is interesting video content by introducing the video, and may adjust the target playing progress to the playing time of the certain period of unplayed video for watching.

Optionally, the target playing progress of this embodiment may also be a position of a played video in the target video. Because a certain speed doubling value is set when the target video is played at the speed doubling value, if the frame number of the video frame skipped by the target video during the speed doubling playing meets the video frame number which needs to be skipped and corresponds to the speed doubling value in unit time, the remaining video frames in the unit time are normally played, and the video content of the normal remaining video frames may be interesting for the user or not. The user can adjust the playing progress of the target video to the playing position corresponding to the played video in the target video, the played video can be the video which is interested by the user, the label of the content type of the played video is obtained, the label is added to the label set, and therefore the label set is updated, so that the label set can be compared with the label of the video frame in the process of playing the target video at the double speed, whether the video frame is the video frame which is interested by the target object or not is judged, whether the video frame is skipped or not is determined, the watching performance of the video is improved, and the efficiency of the video in the double speed playing process is improved.

As an alternative implementation, after skipping the playing of the first video frame in step S204, the method further includes: determining the frame number of a video frame needing to be skipped over when the target video is played at a double speed as a first frame number, wherein the first frame number is determined by the playing speed of the target video when the target video is played at the double speed; determining the frame number of the skipped video frame of the target video as a second frame number; determining the difference between the first frame number and the second frame number as a third frame number, wherein the third frame number is the frame number of a video frame to be skipped by the target video; and under the condition that the third frame number is 0, acquiring a second video frame in the target video frame, wherein the second video frame is the next video frame of the first video frame in the target video.

In this embodiment, in the process of performing double-speed playing on the target video, after skipping playing of the first video frame in unit time, the number of video frames that the target video needs to skip when performing double-speed playing is determined as the first frame number. Optionally, according to a playing speed corresponding to a double-speed value of the target video during double-speed playing, determining a number of video frames that the target video needs to skip in a unit time, for example, determining a number of video frames that the target video needs to skip per second, where the number of video frames that the target video needs to skip per second is the first number of frames, that is, when the number of video frames that the target video needs to skip during double-speed playing is the first number of frames, the playing speed of the target video during double-speed playing is satisfied.

The embodiment determines that the frame number of the video frame skipped by the target video is the second frame number, determines the difference between the first frame number and the second frame number as the third frame number, and the third frame number is the video frame number to be skipped by the target video in unit time, that is, the target video still needs to skip the video frame of the third frame number in unit time to meet the play speed of the target video in the double-speed play, and can enter the motion compensation module to enable the play speed of the target video in the double-speed play to meet the play speed corresponding to the set double-speed value.

If the third frame number is 0, that is, the target video does not need to skip the video frame any more in the unit time, a second video frame in the target video can be obtained, and the second video frame is the next video frame of the first video frame in the target video.

step S302, in the process that the client terminal plays the target video at double speed, the client terminal obtains the label of the first video frame to be played in the target video.

In the technical solution provided in the above step S302 of the present application, in a process that a client performs double-speed playing on a target video, the client obtains a tag of a first video frame to be played in the target video, where the tag of the first video frame is used to indicate a content type of the first video frame.

In this embodiment, the target video may be a video that the user needs to play by the client, and the target video may be played by the video client. The target video is played in a double-speed playing mode.

Optionally, the client sends a target request to the server, where the target request is used for the client to request to obtain the URL of the target video. After the client acquires the URL of the target video, the client acquires the target video according to the URL, for example, the client acquires a video stream of the target video.

Optionally, the target video of this embodiment comprises media package data and audiovisual data. And the client analyzes the media packaging data and the audio and video data in the target video, and if the client plays the target video in a normal playing mode, the client plays the target video until the end.

Optionally, if the client plays the target video in a double-speed playing manner, the client may acquire a first video frame to be played in the target video within a unit time. When the current playing speed of the target video does not meet the speed doubling requirement, the client acquires the tag of the first video frame, for example, the client decodes the target video, and acquires the tag of the first video frame from the obtained decoded data, where the tag of the first video frame may be used to indicate the content type of the first video frame.

Step S304, the client skips playing the first video frame when the tag of the first video frame is different from the preset target tag.

In the technical solution provided in step S304 of the present application, after the client obtains the tag of the first video frame to be played in the target video, the client determines whether the tag of the first video frame is the same as the preset target tag, and the client may determine whether the tag of the first video frame is the same as the preset target tag in the scene matching module. And if the label of the first video frame is different from the preset target label, the client skips the playing of the first video frame.

After the client determines that the tag of the first video frame is different from the preset target tag, if the tag of the first video frame is different from the preset target tag, it indicates that the content type indicated by the tag of the first video frame is not in accordance with the interest of the user, that is, the video content presented during playing of the first video frame is not the video content in which the user is interested, the client skips playing of the first video frame, for example, skips the plot of the video in which the user is not interested at high speed, so that the observability of the target video is improved, and the efficiency of the target video during double-speed playing is improved.

After the client judges whether the label of the first video frame is the same as the preset target label, if the label of the first video frame is the same as the target label, the client plays the first video frame according to the target playing speed, and the difference between the target playing speed and the original playing speed of the first video frame is within a first target threshold value.

In this embodiment, if the tag of the first video frame is the same as the target tag, it indicates that the content type indicated by the tag of the first video frame matches with the interest of the user, that is, the target tag matches with the tag of the first video frame, the video content presented when the first video frame is played is the video content interested by the user, and the client may play the first video frame at the target play speed, that is, the client plays the video content of the first video frame interested by the user at the target play speed. Optionally, the first video frame is played at its original play speed or at a slightly faster speed.

Optionally, in a case that the target video already meets the current speed doubling requirement, the client may play the first video frame at the original play speed of the first video frame; under the condition that the target video frame does not meet the requirement of the current speed doubling, the client can determine the number of video frames needing to be skipped to meet the set speed doubling value according to the set speed doubling value, acquire the number of skipped video frames, determine the difference between the number of the video frames needing to be skipped and the number of the skipped video frames as the number of the video frames needing to be skipped, and determine the target playing speed for playing the first video frame according to the number of the video frames needing to be skipped, wherein the target playing speed is slightly higher than the original playing speed, but the target playing speed and the original playing speed are within a first target threshold, so that the user cannot influence the user to watch the interested video content in the target video.

Optionally, in this embodiment, in unit time, when the number of frames of video frames that have been skipped by the client reaches the number of video frames that need to be skipped and correspond to the double-speed value of the target video, the remaining unplayed video frames in unit time may be played normally, and the remaining unplayed video frames may include video frames that are interesting to the user or may include video frames that are not interesting to the user; if the determined frame number of the skipped video frame does not reach the video frame number which needs to be skipped and corresponds to the double speed value of the target video in unit time, the client can further enter a motion compensation module to select the skipped frame according to the similarity between the adjacent video frames, skip one video frame of the two adjacent video frames with high similarity and play the other video frame, thereby determining the video frame which needs to be skipped and the video frame which needs to be played in unit time by the client so as to meet the playing speed of the target video in double speed playing.

The client selects to skip or play the video frame of the target video according to the method in one unit time, and can also select to skip or play the video frame of the target video according to the method in the next unit time, so that the content which is interested by the user in the target video is displayed to the user to the maximum extent, and the efficiency of the video in double-speed playing is improved.

Through the steps S302 to S306, in the process that the client performs double-speed playing on the target video, the client acquires a tag of a first video frame to be played in the target video, wherein the tag of the first video frame is used for indicating the content type of the first video frame; under the condition that the label of the first video frame is different from the preset target label, the client skips the playing of the first video frame; and under the condition that the label of the first video frame is the same as the target label, the client plays the first video frame according to the target playing speed, wherein the difference between the target playing speed and the original playing speed of the first video frame is within a first target threshold value. After the target video is played at double speed, the client skips over the first video frame with the label different from the preset target label, and plays the first video frame with the label identical to the preset target label at the target playing speed, that is, the client skips over the video frame which is not interested by the user, and plays the video frame which is interested by the user at the target playing speed, so that the technical effect of improving the efficiency of the video at double speed playing is realized, and the technical problem of low efficiency of the related technology at the video at double speed playing is solved.

The embodiment can distinguish the content of the target video by using an artificial intelligence algorithm, and after the target video is played at a double speed, the video content which is interested by the user is played at the original speed or is played at a slightly higher speed, and the video content which is not interested by the user is skipped at a higher speed. The similar video frame between adjacent video frames can be skipped over in an artificial intelligence mode to further improve the user experience, so that the double-speed watching experience of the user on the video is improved, the wonderful content of the video can be displayed to the user to the maximum extent, and the efficiency of the video in double-speed playing is improved.

step S501, a first frame image of the video is analyzed, and a label of the extracted first frame image is K0.

In the embodiment, transcoding is started for the video source through the transcoding server, and the video source enters the intelligent calibration module. The first frame image of the video may be analyzed based on the visual library OpenCV, the label of the extracted first frame image is K0, and the settings are grouped as S0. OpenCV is a cross-platform computer vision library, which can run on an operating system.

Step S502, analyzing the second frame image of the video, and extracting the label of the second frame image as K.

A new frame of image is read, analyzed using OpenCV, and the tag is extracted as K.

In step S503, it is determined whether the label K0 of the first frame image is the same as the label K of the second frame image.

After the second frame image of the video is analyzed and the label K of the second frame image is extracted, it is determined whether the label K0 of the first frame image is the same as the label K of the second frame image. If it is determined that the tab K0 of the first frame image is identical to the tab K of the second frame image, step S504 is performed, and if it is determined that the tab K0 of the first frame image is not identical to the tab K of the second frame image, step S505 is performed.

Step S504, adding the second frame image to the packet to which the first frame image belongs, where the label is the label of the packet.

After judging whether the label K0 of the first frame image is the same as the label K of the second frame image, if the label K0 of the first frame image is the same as the label K of the second frame image, the second frame image is added to the group to which the first frame image belongs, the label being the label of this group.

In step S505, the second frame image is set to belong to the new packet Sn.

After judging whether the label K0 of the first frame image is the same as the label K of the second frame image, if the label K0 of the first frame image is not the same as the label K of the second frame image, the second frame image is set to belong to the new group Sn. The previous grouping S0 completes the grouping.

And S506, exiting the intelligent calibration module.

And step S507, continuing to finish transcoding of the video.

Step S508, determine whether transcoding is completed.

If the transcoding is not completed, executing the method after the step S501, and continuously grouping a plurality of video frames in the video; if the transcoding is not completed, the execution flow is ended.

Fig. 6 is a schematic diagram of a transcoding server according to an embodiment of the present invention. As shown in fig. 6, a media encoder in the transcoding server acquires media data sent by an audio/video input device, encodes the media data to obtain a video stream, and inputs the video stream into a server having a HyperText transfer Protocol (HTTP) to process the video stream into a certain type of media file. And the video stream is distributed to a webpage server and is sent to a client through an HTTP protocol, so that the video source is transcoded.

And the scene matching module 2 is used for comparing the label of each frame with the interest label of the user and selectively skipping the unmatched video frame according to the double speed if the user plays the video at the double speed in the playing process of the player.

And the motion compensation module 3 enters the motion compensation module 3 after skipping frames through the scene matching module if the requirement of the target video in double-speed playing cannot be met. The motion compensation module 3 essentially predetermines a window determined from successive frames having the same label. The window size is the number of consecutive frames with the same label. Starting with the second video frame in the window, calculating whether the similarity between the two continuous video frames exceeds a threshold value according to the correlation between the previous video frame and the current video frame, if so, considering that the similarity between the two video frames is higher, and selecting one of the two video frames with poor playing quality to skip. Alternatively, the threshold value of this embodiment may be determined according to the double speed value currently set by the video.

And the behavior statistical module 4 is used for analyzing the behaviors of the user at the double speed and the video tags each time to continuously update the interest tags of the user so as to match the user behaviors during subsequent video playing at the double speed.

In this embodiment, the user's viewing behavior may be counted by the backend server, and the user's interest may be calibrated, for example, the user's behavior may be calibrated to be people, landscape, gunfight, martial arts, love, beauty, and the like, without any limitation here.

The following describes the player of this embodiment.

Fig. 7 is a flowchart of a video playing method of a player according to an embodiment of the present invention. As shown in fig. 7, the method comprises the steps of:

step S701 requests the URL of the target video.

The URL of the target video is requested according to the user's needs. And requesting the video stream of the target video from the server according to the URL of the target video.

Step S702, receiving the video stream sent by the server.

Step S703, the media package data and the audio/video data in the video stream are analyzed.

Step S704, detecting whether the target video sets a double-speed playing.

If detecting that the target video is not set to play at double speed, executing step S705; if it is detected that the target video is set to double-speed play, step S706 is performed.

Step S705, the normal play is performed until the play is finished.

Step S706, a current video frame of the target video is acquired in unit time.

Step S707, in case that the target video needs to be doubled, acquiring the label of the current video frame.

Under the condition that the target video needs to be subjected to double speed, the current video frame can be decoded to obtain the label of the current video frame.

Step S708, determine whether the tag of the current video frame is the same as the user interest tag.

After the label of the current video frame is obtained, whether the label of the current video frame is the same as the user interest label is judged. If the label of the current video frame is judged to be the same as the user interest label, executing the step S709; if the tag of the current video frame is not the same as the user interest tag, step S710 is performed.

Step S709, play the current video frame.

In step S710, the current video frame is skipped.

In step S711, the frame number Tn of the video frame that needs to be skipped in the unit time is acquired.

The number of frames of the video frame to be skipped in a unit time can be determined according to the double speed value set by the current target video, and the difference between the number of frames of the video frame to be skipped in the unit time and the number of frames of the video frame to be skipped currently is determined as the number of frames Tn of the video frame to be skipped.

In step S712, it is determined whether Tn is equal to 0.

After the frame number Tn of a video frame which needs to be skipped in a unit time is acquired, whether Tn is larger than 0 is judged. If Tn is not equal to 0, go to step S713; if Tn is equal to 0, go to step S706.

In step S713, the remaining number of frames Y0 of the S group in which the current video frame exists is acquired.

After judging whether Tn is greater than 0, if Tn is not equal to 0, the remaining frame number Y0 of the S group where the current video frame is located is obtained.

In step S714, it is judged whether or not the remaining frame number Y0 is equal to 0.

After the remaining frame number Y0 of the S group where the current video frame is located is acquired, it is judged whether the remaining frame number Y0 is equal to 0. If the remaining frame number Y0 is judged to be equal to 0, executing the step S706; if it is judged that the remaining frame number Y0 is not equal to 0, step S715 is performed.

In step S715, the frame skipping coefficient V0 and the target value T0 are acquired according to the currently set double speed value.

After judging whether the remaining frame number Y0 is equal to 0, if it is judged that the remaining frame number Y0 is not equal to 0, the frame skipping coefficient V0 and the target value T0 are obtained according to the currently set speed doubling value, and T0 × V0 is determined as the threshold.

Step S716, enter the motion compensation module, and obtain a new current video frame.

In step S717, the new current video frame and the next video frame are analyzed to obtain the similarity between the current video frame and the next video frame.

After analyzing the new current video frame and the next video frame to obtain the similarity between the current video frame and the next video frame, judging whether the similarity between the current video frame and the next video frame exceeds a threshold value T0V 0. If the similarity between the current video frame and the next video frame is judged to exceed the threshold value T0 × V0, executing step S719; if the similarity between the current video frame and the next video frame is not greater than the threshold T0V 0, step S713 is executed.

In step S719, a new current video frame is skipped.

The behavior statistics module 4 of this embodiment may update the matching tag in the speed doubling process of the user. Optionally, if the user drags to the relevant position again for viewing after playing at double speed, the tag at the current position is analyzed, and the interest tag of the user is updated.

The double-speed playing device provided by the embodiment can distinguish the contents of the video by applying an artificial intelligent algorithm. After the video uses the double-speed play function, the content that is interested in the user is played at the original speed or is played at a slightly faster speed, and the content that is not interested in the user is skipped at a higher speed.
